摘要： A method is described for controlling the combustion in a gas turbine. The method comprises the phases of measuring, by means of one or more probes (30) situated in correspondence with the combustion chamber (14) of the turbine, the amplitude of the pressure oscillations inside the combustion chamber (14) and the persistence time or cycle of the same oscillations, evaluating the behaviour under fatigue conditions of the combustion chamber (14), by constructing the Wohler curve for a certain material which forms the combustion chamber (14) for a predefined combustion frequency and for the amplitude and cycle values of the pressure oscillations measured, measuring the cumulative damage (D) to the combustion chamber (14) during functioning under fatigue conditions of the turbine by means of the Palmgren-Miner hypothesis and exerting protection actions of the turbine if the cumulative damage value (D) measured is exceeded.

摘要： Apparatuses and methods for constructively use pressure pulses to enhance the volumetric efficiency of a reciprocating compressor are provided. An apparatus includes a gas circulation device and a controller 110. The gas circulation device provides a path through which the gas circulates between a reciprocating compressor 10 and a volume bottle 50 buffering the reciprocating compressor from an installation. The gas circulation device is configured to have to have a resonance frequency substantially equal to a frequency of performing compression cycles in the reciprocating compressor. The controller 110 is configured to control timing of switching a valve located between the reciprocating compressor and the gas circulation device, in order to use constructively pressure pulsations occurring in the gas circulation device, to enhance the volumetric efficiency of the reciprocating compressor.

摘要： An actuated rotary valves for reciprocating compressors used in oil and gas industry, the valve including a stator with a stator opening, a rotor with a rotor opening, and an actuation mechanism. The actuation mechanism is configured to receive a rotation motion and to actuate the rotor to perform first an axial translation moving away from the stator and then a rotation. The actuation mechanism includes an outer shaft configured to receive the rotation motion, and an inner shaft inside the outer shaft and configured to rotate the rotor. The outer shaft is configured to rotate a predetermined angular displacement while pushing the rotor away from the stator before engaging the inner shaft to rotate together with the rotor.
